TEENAGE twins boasted about killing their grandmother to their 14-year-old Internet girlfriends, a court heard yesterday.

Robert and Jonathan Maskell are accused of murdering 74-year-old Anjelica Hallwood for her £2,000 savings on their 18th birthday.

They are said to have recruited friend Dwane Johnston, 19, to help with the robbery after he got out of prison.

But the pair could not resist telling two girls they regularly chatted to on the computer programme MSN Messenger of their plans, it is claimed.

The girls, now 15, talked to the brothers every day from their homes in Darlington.

One told the Old Bailey she had sex chats with Robert Maskell from July last year and even planned to run away to see the pair in Edmonton, north London.

She said: "He was just saying he wanted to sleep with me. I just agreed to it.

"I planned to run away because I felt the whole world was on top of me, but we only got as far as the train station."

She said she finished with Robert after the plan fell apart, but kept in contact until after the alleged murder on January 28 this year.

She said: "Robert said he had killed his grandmother, beaten her up and hit her with a hammer.

"Jonathan also said it as well. I thought they were lying because they were like bragging. I did not believe it.

"At first he told me Dwane had done it and they stood there and watched. Then he said 'We have killed her'."

The second teenager told jurors that Jonathan Maskell told her he was in love with her and wanted to have children with her.

She said: "He told me they had killed their nana. He also said he had cancer and he was going to hang himself."

The twins and Johnston allegedly left their birthday party at 11pm to rob Mrs Hallwood at her home in Edmonton. Her body was found by her granddaughter the next morning. A post-mortem examination found evidence of a punch to the face, fractures to her chest and signs of asphyxiation.

The twins later said they had waited outside the house and were then handed the money by Johnston as he left.

Johnston, of Granville Avenue, Edmonton, and the Maskells, both of Chalfont Road, Edmonton, deny murder. The Maskells also deny robbery. The trial continues.
